There has been lots of discussions on various sites regarding the problems with the Oshkosh (Kings) trailers, apparently all the rollovers have occured at low speeds and if I remember correctly theres been a problem with the trailer hydraulics causing them to lean/fail quite badly, obviously with 60/70 tons on board this has disastrous results.
As for recovery, the Army has the equipment and expertise but I would think it's due to the fact that all recovery is carried out by civilian recovery contractors, a very sore point with Army recovery mechanics:mad:
